There are provided a method and apparatus for video error concealment using high level syntax reference views in multi-view coded video. The apparatus includes a decoder for decoding pictures for at least one view corresponding to multi-view video content from a bitstream. The pictures are representative of at least a portion of a video sequence. At least some of the pictures correspond to different time instances in the video sequence. The decoder determines whether any of the pictures corresponding to a particular one of the different time instances are lost using an existing syntax element. The existing syntax element is for indicating at least one reference view used for inter-view prediction of at least one of the pictures.

Implementations are provided that relate, for example, to view tiling in video encoding and decoding. A particular method includes accessing a video picture that includes multiple pictures combined into a single picture, accessing information indicating how the multiple pictures in the accessed video picture are combined, decoding the video picture to provide a decoded representation of at least one of the multiple pictures, and providing the accessed information and the decoded video picture as output. Some other implementations format or process the information that indicates how multiple pictures included in a single video picture are combined into the single video picture, and format or process an encoded representation of the combined multiple pictures.

There are provided methods and apparatus for use in multi-view video coding. An apparatus includes an encoder for encoding anchor and non-anchor pictures for at least two views corresponding to multi-view video content, wherein a dependency structure of each non-anchor picture in a set of non-anchor pictures disposed between a previous anchor picture and a next anchor picture in display order in at least one of the at least two views is the same as the previous anchor picture or the next anchor picture in display order.

There are provided method and apparatus for use in a multi-view video coding system. The apparatus includes an encoder for encoding at least two views corresponding to multi-view video content into a resultant bitstream, wherein the resultant bitstream is encoded to include view specific information. The view specific information indicates a decoding interdependency between at least some of the at least two views.

There are provided methods and apparatus for signaling view scalability in multi-view video coding. An apparatus includes an encoder for encoding at least one picture for at least one view corresponding to multi-view video content in a resultant bitstream. The encoder signals at least one of a view direction and a view level to support view scalability for the at least one view using at least one of a message, a field, a flag, and a syntax element.

There are provided scalable video encoder and decoders, and corresponding scalable video encoding and decoding methods. A scalable video encoder includes an encoder for encoding a block in an enhancement layer of a picture by applying a same weighting parameter to an enhancement layer reference picture as that applied to a lower layer reference picture used for encoding a block in a lower layer of the picture. The block in the enhancement layer corresponds to the block in the lower layer, and the enhancement layer reference picture corresponds to the lower layer reference picture. The scalable video decoder includes a decoder for decoding a block in an enhancement layer of a picture by applying a same weighting parameter to an enhancement layer reference picture as that applied to a lower layer reference picture used for decoding a block in a lower layer of the picture. The block in the enhancement layer corresponds to the block in the lower layer, and the enhancement layer reference picture corresponds to the lower layer reference picture.

There are provided methods and apparatus supporting a multi-pass video structure for slice data. An apparatus includes an encoder for encoding at least one syntax data element related to at least two partitions of at least a portion of a picture. The at least one syntax element is encoded within a multi-pass syntax structure. The at least one syntax element belongs to a given class of data. The encoder encodes the at least one syntax data element with respect to all partitions of at least the portion of the picture prior to encoding a next class of data, wherein later coded data classes, including the next class, have at least one of an explicit coding and an implicit coding of at least one of a casual dependency and a non-casual dependency with respect to earlier coded data classes coded earlier than the next class.

Various implementations are described. Several implementations relate to a refined depth map. According to one aspect, depth information for a picture in a set of pictures is accessed. Modified depth information for the picture is accessed. A refinement is determined that characterizes a difference between the depth information and the modified depth information. The refinement, and the depth information, is provided for use in processing one or more pictures in the set of pictures.

A picture reference list ordering process is defined for a multiview coder for coding moving pictures, where the picture list has the coding order of reference pictures used to code a picture specified in relationship to whether a picture to be coded is associated with a view. The ordering of the picture list will therefore change the coding order of the reference pictures in the picture reference list depending on the temporal relationships the reference pictures have with the picture to be coded and views associated with the reference picture.

Various implementations are described. Several implementations relate to one or more encoding modes that use depth information to determine a corresponding reference block. According to a general aspect, a portion of a first-view image from a first view in a multiple-view system is encoded. The portion is all or part of the first-view image. It is determined that a portion of a second-view image from a second view in the multiple-view system corresponds to the portion of the first-view image. The determination is based on a second-view depth value providing depth information for the portion of the second-view image. The portion of the second-view image is encoded using information from the encoding of the portion of the first-view image.
